SUPERNOVA 2008ax IN NGC 4490
     W. Li and A. V. Filippenko, University of California, Berkeley, write
that follow-up observations of SN 2008ax show that, after an initial decline
in the B band between Mar. 4 and 5 UT, the supernova has been steadily
brightening since discovery, with B = 15.3, V = 14.6, and R = 14.1 on Mar.
12.48.  This is approximately 2 mag brighter than at discovery (cf. CBET
1280).  The brightening rate of 2008ax is about three times that of the
type-IIb supernova 1993J.
